C-H,
Thanks for the pic, mate.
This sort of thing is pretty much common-place over here in NZ, these days, and depending on who disconnected the fitting, sometimes, you're lucky if they have tape on them, for a start.
Electricians are very hard to get over here at the moment, we have to concentrate more on the Industrial things, rather than the smaller jobs, there are just not enough Sparkies to go around!. [Linked Image]
